Some advanced systems overlay the digital twin onto te te fizycal machine using augmented reality (AR). An operator wearing smart glasses can see the virtual mold 's internal temperatur distribution superimposed on thee actual press, making it easyr to identify hot spots or cool imbalances.
Process Optimization via Simulation
One of thee most powerful uses of a digital twin is what-if analysis. Engineers can pause thee fizycal line and run hundreds of simulation simulation on the twin - changing charge waxt, temperatur setpoints, or closing speeds - to find the optimal recipe for a new material or part dexine. Because the twin has been kalibrated with real sensor data, its preventions are far more reliable than a generic simulation run offline.
For example, a developer chandising from a standard SMC to a low- density comclond can use thee twin two predict flow behavor and cure time adjustments before cutting a single charge. This reduces trial- and- error on the press andd cuts develoment lead time by weeks.
